Just when the two were dumbfounded, Li Xuan smiled faintly, sprinkled a seed casually, and then summoned a heavy rain.

Originally, the place where the sword sprouts and rice fields were originally located had now become a green grassland, and a large area of blue, silver, grass and green was crystal gratifying, and the wisps of aura were suddenly transformed and released.

It can be clearly perceived that the concentration of spiritual energy in this space is increasing rapidly, and the various medicinal herbs and crops growing in other fields are also becoming stronger.

All kinds of flower bones compete to open, and the rich medicinal fragrance wafts out.

Seeing this scene......

Long Aotian and Dongfang Yu couldn't help but tremble all over their bodies, and their mouths opened wide, as if they had seen the most incredible thing in the world.

"This ...... Reiki!"

Long Aotian shouted without an image, his eyes were round, and he shouted in disbelief.

Since ancient times, the growth of heaven and earth treasures has always consumed the aura of heaven and earth, and I have never seen such a thing, but it can produce the aura of heaven and earth!

You must know that the purpose of the establishment of the Crystal Palace is to protect the recovery of the terrestrial spiritual vein, if there is a sufficient amount of this grass, the spiritual energy recovery is just around the corner!

For a while, Long Aotian's eyes were also extremely hot.

Compared to this grass, what is a little sword bud rice?

Li Daoyou ...... What kind of grass is this, what kind of grass is this?"

The sharp Adam's apple shook twice, and Long Aotian asked in a trembling voice.

"Blue Silver Grass, it can transform aura, as for efficiency, you've seen it. Li Xuan said casually, shaking his head and smiling.

I didn't expect these two people to react so much.

However, it is also normal that in this era of the end of the Dharma, a small handful of Blue Silver Grass seeds can create a Cave Heaven and Blessed Land, which is naturally a coveted treasure for cultivators.

"Blue Silver Grass...... Blue Silver Grass ......"

Long Aotian muttered softly, and suddenly bowed deeply to Li Xuan, and said in a deep voice: "With this blue silver grass, the revival of the aura is just around the corner, the old man is here, thank you to the seniors, all the cultivators in this world will remember the great kindness of the predecessors." ”

He said very seriously, with the brilliance of an idealist in his eyes.

Well?

Hearing his words, Li Xuan's heart moved slightly, and he couldn't help but speak: "I've heard someone say before that you are studying the undersea aura and want to lead the global aura recovery?"

Long Aotian nodded.

"Exactly, I have been studying the undersea aura layer recently, the heavens and the earth have changed greatly, and many spiritual veins have been sealed in the depths of the seabed, once released, it will definitely reappear in the grand occasion of the cultivation world. ”

That's right.

Li Xuan glanced at him, still thinking that this idea was ridiculous.

"Is there a grand occasion in the cultivation world? This world has never been dominated by mortals?"

Li Xuan's question made Long Aotian stunned for a moment, came back to his senses, and quickly defended: "Yes, yes, but that's because my generation of monks only seek immortality, and they have no interest in Wanzhang Hongchen." ”

"Fart!"

Li Xuan reprimanded.

"In terms of operational efficiency alone, the state is definitely the most efficient organization, and if, as you said, the cultivation world was once prosperous, then why has there never been a cultivation country? Qin, Han, Yuan, Ming, and Qing dynasties...... Which dynasty was born because of the practitioners?"

In the past five thousand years, Li Xuan has seen too many civilizations, and his insights and cognitions on this matter are of course much deeper than those of the two.

It can be said that it is not on the same level at all.

At this moment, Li Xuan's question was like a slap in the face, making both of them look confused in their eyes.

It's a scary question.

"Because there are too few cultivators, the aura of heaven and earth is still not enough!"

Long Aotian searched for dry intestines, but still gritted his teeth and said.

This is the only answer.

Li Xuan smiled faintly and said softly: "Congratulations on your correct answer, then what do you think should be done?"

"Of course!"

Long Aotian said subconsciously, but as soon as the words came out, he faintly felt that something was wrong, but what was wrong, he couldn't help but fall into the blind spot of thinking.

Then, he heard Li Xuan's voice.

"From the perspective of mythology, in ancient times, there was Pangu to open the sky, Houyi shot the sun, in ancient times, there was the Yellow Emperor Chiyou War, and then there was the Battle of the Gods, and then there was the pre-Qin Qi Refiner...... I found that no, the monks were weaker from generation to generation, because this world could not accommodate many powerful beings. Or it can be said that the predecessors have accumulated the cultivation resources of the later generations. ”

Long Aotian sighed and nodded slightly.

Li Xuan asked again: "However, what if the aura of heaven and earth is extremely strong, it is enough for anyone to use, inexhaustible, inexhaustible, what should we do?"

Long Aotian was silent for a moment, and said in a low and firm voice: "Everyone in the world is like a dragon, cultivating their own avenues. ”

As soon as the words came out, he saw Li Xuan's eyes as if he was looking at an idiot, the corners of his mouth twitched twice, and he also smiled bitterly: "Li Daoyou, just say it." ”

Li Xuandao: "There was also a time when it was called a wilderness, and compared with other powerful species, human beings grew too slowly, and their bodies were too weak, so that there were very few of them, and they could only survive. It was the best of times and the worst of times. And you, in those times, how long can you live?"

Such a rhetorical question was really like a thunderbolt, and when it was slashed, Long Aotian was stunned, but he felt that what Li Xuan said was right.

The intensity of the aura has created the status of each species.

In the era of dinosaur domination, the aura of heaven and earth was absolutely rich to the extreme, but human beings had no room to survive at all.

Now, with the thinness of the earth's aura, countless alien beasts cannot survive, so human beings can achieve a brilliant scientific and technological civilization.

"That ......"

Burst!

Long Aotian suddenly spurted blood fiercely, and his white beard was dyed red, as if he had fallen into some kind of inner demon.

The revival of aura is the greatest significance of the existence of the Crystal Palace, and it is also the cause for which he has fought all his life.

And now, I hear such a point.

There is nothing wrong with the path I am taking, but this incident itself may be a mistake.

"People live for a lifetime, plants and trees for a lifetime, just seek the present, enough, enough. ”

Li Xuan said softly, and immediately beckoned to Dongfang Yu: "Let's go, take me to see the classics." ”

Dongfang Yu glanced at the palace master with some concern, only to see him standing in place, falling into some kind of contemplation, his fingers moved quickly, and he didn't figure out the reason for it.

Li Xuan's words, although they also shocked him in his heart, were far less powerful than Long Aotian.

Dongfang Yu was originally a person who was at ease with what happened.

"Let's go, senior, I'll take you in. ”

With a long sigh, he stretched out his hand to invite.

Li Xuan nodded and strode into the gate of the Crystal Palace.

At this time, I probably heard movement outside, and a person rushed out inside.

It was Tang Lian.

Seeing Li Xuan, she was stunned, like a sculpture, standing there, not moving, her eyes were extremely complicated.
